Show HN: Wormhole.page – Magic Wormhole file transfer in the browser via WASM • Hacker News Board

Magic Wormhole is great but requires a CLI or app. I put a full wormhole-rs client in the browser via WebAssembly so you can send E2E encrypted files to anyone — interoperable with all standard wormhole CLIs.

Drop a file, get a code, other person opens the link or types wormhole-rs receive . SPAKE2 + NaCl encryption happens client-side, the server only bridges WebSocket transit.

Built this as an experiment with Claude Code + gstack. All code written by Claude. Single Rust binary, vanilla JS, no framework.
